Recently I have been hearing a weird buzzing noise in my room and I just figured out it was my computer. I tried opening it up and pinpointing the noise but there was no noise when I tried. I figured out it only happens when I'm playing a game so I imagine it is something to do with my GPU or CPU fans, but I am not sure. I started up a bot game in overwatch and started recording right when the noise happened which was after i put the side cover back on and the fighting with the bots began. I alt-f4 out of overwatch to show it goes away right when program stops running.

Well that sounds like some really hideous coil whine. Its probably coming from your gpu or psu. If I had to guess that's the power supply, I have never heard a gpu make a noise like that. What power supply do you have?
1. Let the bugs out :)

2. Look for some youtube recordings of "coil whine", make sure that's not it.

3. When ya run outta paper towels next time, save the cardboard tube. Holding this to your ear with the other end at various locations inside the case can narrow it down.

4. Unplug or place a finger on each fan to stop it and see if sound stops.

5. make sure no older GSM phones nearby

EDIT: Just realized that you had recorded it ... duh.

That sounds like a fan hitting the shroud on GPU.

if it is that, anything I can do to fix it besides getting a new GPU?
 


That buzzing sound? That does not sound like a fan to me or anything mechanical, it sounds like a quite loud electrical buzzing noise.
 
1. First confirm that it is the problem ... if it stops when ya put finger on one of the fans, you found the problem. May need to give it a push to get going again.

2. If that's it, take the card out and turn fan with fingers,. If ya see the fan blades hitting the shroud anywhere, mark the location with a 'sharpie'. Then use an exacto knife to trip the mark .
 


if that was the problem I feel like it would be happening all the time, not just when playing something graphic/CPU intensive.
 
Today's GFX cards are equipped with fan control which a) stops the fans ... at low loads they don't spin and b) they typically blow air down, which when you have a loose bearing can lift the blades. Check this out with ya case fans when off ... if ya grab the hub, you can move the fan in and out a teeny bit along the shaft.... So at one end of this range of movement, you may be fine.... at the other end, it hits.

I had a case fan that did this. It was a Phanteks F-140SP installed horizontally and it blew air down thru the radiator. It was fine up to about 750 rpm. Buy when it got past that when the fans pushed air down, the blades got pushed up...so when rpm varied according to the fan curve, the blade assembly would go up and ... when it came back down and hit the "shaft stop" it made a noise. Going up / down / up / down it made a chatter noise from the repeated banging against the stop. I called Phanteks for an RMA and they told me to keep the fan (I later swapped it to a vertical mounting location and it was fine) and they sent me 2 new pones "for my trouble".

So yes, since the condition at idle may be idle or slow rpm, the start of something GFX intensive will in fact either start the fans spinning or spin them faster, either of which can cause the noise. I'd also note that coil whine behaves the same way ... the ore juice going thru the card the louder the noise gets.
 


ok i will test it out when I can
 


It ended it up being coil whine on GPU, totally gone since I got a new card
